Electrolysis on Breast

I am getting electrolysis on my breast (the full breast, not just around the nipples). The hairs are long, fine and I see that for some follicles, there are more than one hair growing out. My electrolysis is using Thermolysis.

Is Thermolysis the best type of electrolysis to use? Do you know how many 1 hour sessions it might take for the initial clear and subsequent sessions to fully clear?
